What the specs work out to

Figures MowerFacts computes from Kubota’s own numbers — not published by the manufacturer.

Mowing time

  • ¼ acre3 min 2 min
  • ½ acre7 min 5 min
  • 1 acre14 min 10 min
  • 2 acres28 min 20 min
  • 5 acres1 h 10 min 49 min
  • 10 acres2 h 20 min 1 h 38 min

About 14 min per acre at 4.3 acres/hour, mowing at 7.4 mph. The second figure is at the published 10.6 mph top speed (6.14 acres/hour) — faster than anyone really mows. About 55.5 acres per tank.

Weight & hauling

  • Machine weight1,742 lb
  • + 6×12 trailer900 lb
  • Towed weight2,642 lb
  • single-axle 3,500 lbCarries it, 858 lb spare
  • tandem-axle 7,000 lbCarries it, 4,358 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,642 lb.

Gate & trailer fit

  • 32 in gateToo wide
  • 36 in gateToo wide
  • 48 in gateToo wide

Needs at least 86 in of clearance.

Power & run time

  • Power per deck inch0.404 hp/in
  • Run time per tank~12.9 h

Mowing times assume 4.3 acres/hour: deck width x 7.4 mph at 80% efficiency, which allows for overlap, turns and trimming. 7.4 mph is 70% of the 10.6 mph top speed Kubota publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 10.6 mph, shown so you can see it.

Fit uses Kubota's published overall width.

Towed weight adds a 900 lb allowance for a 6x12 open utility trailer to Kubota's published machine weight. Your trailer's own weight is on its VIN plate. Tongue weight, axle placement and your vehicle's tow rating are still yours to check — this is the load, not a loading plan.

Run time assumes a typical 1 gal/hour burn at working load; real consumption varies with engine, load and cut.
